JPEGIFICATION forming part of Letters Patent No. 437,400, dated September 30, 1890. I Application filed March 26, 1890. Serial No. 345,456. (No model.) E

To all whom, it may concern.-

Be it known that we, GEORGE MARTIN and LATHARO ll/IORGAN FRIAR, both of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Car-Couplings; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application. In our improvement filling-blocks are used, which are inserted in the mouths of the ordinary draw-heads and held in place by pins inserted through tongues of the filling-blocks and the draw-heads. To one of the fillingblocks is attached a pivoted link and to the other a hook. To the filling-block having the link is also attached a pivoted triggenwhich, when the draw-heads strike together, springs the link and throws it over into engagement with the hooks.

The'invention consists in the construction and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the ends of two cars, one approaching the other, and showing the coupling set ready for engagement. Fig. 2 is an enlarged central vertical section of the ends of the two draw-heads and the coupling set ready for engagement. Fig. 3 is a perspective view of the filling-block to which the pivoted link and trigger are attached and showing said parts connected therewith. Fig. 4 is a perspective View of the opposite filling-block to which the hook is attached. Fig. 5 is afront elevation of a car with the coupling attached thereto, and showing more particularly the means for raising and uncoupling the links without going between the cars. Fig. 6 is a plan view of the two draw-heads with couplings attached, showing a modification. Fig. 7 is a central vertical section of Fig. 6, but showing the coupling disengaged. Fig. 8 is a cross-section of one of the draw-bars, and Fig. 9 a detail.

A and A indicate the ordinary draw-bars now in use, the same being attached to the cars B B in the usual way.

0 and D are two filling-blocks, which are fitted into the open mouths of the draw-heads and serve as the attachment for the couplings. The object is to enable an improved coupling to be attached to the common draw-heads. Hence the filling-blocks are fitted to theheads and the coupling devices are fitted to the fill ing-blocks. r

The filling block 0 consists of the faceblock 0, that extends vertically across the draw-head and abuts its front end. To this is attached a tongue-piece O, that extends into the open mouth far enough to receive the coupling-pin E, which passes through the ordinary holes of the head and a hole in the tonguepiece. The bottom of thisv tonguepiece is beveled on the under side, as shown at a, Figs. 2 and 3, to fill the corresponding top of the block 0 is also pivoted at b a secondary tongue-piece G which extends back over the top of the draw-head, and has a hole through which the coupling-pin E also passes. The filling-block is therefore attached to the draw-head by two separate bearings, which hold it steadily in place and also produce equal strain and hold the filling-blocksquarely in place under tension. The upper tonguepiece 0 by being pivoted, enables the fillingblock to be easily and readily fitted in place.

F is a link attached to the filling-block O and forming the coupling on one side. It has a straight bearing a, Fig. 3, that passes through a hole in the block, and is capable of turning up and down. It is held on the back side of the filling-block by cap-pieces d d, screwed to the block. It also has on the under side and within the block a lug or pro jection f, Fig. 2, against which rests the pivotal trigger, presently to be described. When the cars are uncoupled, thelink is set in the upright position shown in Fig. 2 and the lug f stands downward. I

G is the trigger, the same consisting of a block pivoted at g in a slot of the fillingblock, its upper end resting against the lug f of the link and its face standing out in ad- Vance of the filling-block and in position to be struck and forced in by the opposite drawhead. \Vhen so forced in, it strikes lug f and throws the link forward and downward to engage with the hook on the other drawhead.

bevel in the mouth of the draw-head. In the.

The opposite filling-block consists of a faceplate D, which covers the whole face of the draw-head, and a single tongue-piece D of similar shape to C, but provided with a square hole It instead of a round hole, to receive a square portion of the coupling-pin E, which rests therein to prevent the pin from turning and displacing the hook. The hook E which forms the coupling on that side, is attached to the top of the pin E and stands reversely to the link to allow the link to engage therewith when thrown down, as before described. By thus attaching the hook directly to the pin the pin and hook can be changed from one car to another by simply dropping the pin through the holes in the draw-head. The face-plate D is of such size that when the cars come togetherit is sure to strike the trigger G and spring the link to engage the coupling. The coupling-pins may be held in place by keys 2' 2', as shown.

By the arrangement above described it will be seen that the new coupling is adapted to old draw-heads and that it is self-coupling when the cars come together. It will also be seen that the attachments can be shifted from one car to another with but little trouble.

The uncoupling of the cars is accomplished without going between the cars by the following means: H, Fig. 5, is a chain or cable attached to one side of the link F and extending to the top of the car through loops or over pulleys m m. By this means the coupling-link can be raised to disconnect the coupling, both at the top and the sides of the cars.

Figs. 6 and 7 show modifications in which the links are supplemented by armed hooks I I, pivoted on pins or bolts K K, which pass horizontally through the draw-heads. Either the hooks or links may be used. When the hooks are used, the link is turned down, as shown at the left in Fig. 7, so as to hang out of the way, and thehooks are turned up. The lower ends of the hook-arms project outward, as shown at p p, and when the cars come together the opposite draw-heads strike these projections and spring the hooks forward, so that they engage with the pins K K; A double coupling is thus produced on opposite sides. The draw-heads in this case are made in different form from the old draw-heads, being wider to give room for the hooks and links, and being also provided with rubber springs r having iron washers s s between them. Fig. 9 shows double pulleys m m in a case, over which two branch chains or cords H H pass to the sides of the carsto enable the links and hooks to be operatedin uncoupling.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a car-coupling, the combination, with the draw-heads, of the filling-blocks O D, attached to the draw-heads by coupling-pins, the link F, pivoted to the blocks 0, so as to turn up and down, and provided with the projecting lug f, the trigger G, pivoted to block 0, bearing against the lug and projecting out.- ward from the draw-head, and the hook E attached to the opposite draw-head from that which has the link, as shown and described, and for the purpose specified.

2. In a car-coupling, the combination, with the filling-block C, of the fixed tongue-piece G, adapted to enter the mouth of the drawhead, and the supplementary tongue-piece C pivoted to the block and adapted to pass over the top of the draw-head, said tongue-pieces provided with holes for the passage of the coupling-pin, as herein shown and described.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
